    Hey guys,

    I bought crysis 2 for windows a while a go, but didn't have time to play it until now, I'm a bit worried about the temperatures though. I played for about 30 minutes under bootcamp and these are the results:

    CPU core 1: average 90° C max: 104 °C
    CPU core 2: average 90° C max: 101 °C
    CPU core 3: average 90° C max: 104 °C
    CPU core 4: average 90° C max: 101 °C

    GPU core: average 80° C max 90° C

    104° C is whats worrying me, I see no references on the rMBP temperature parameters. Are these normal?

    it is absolutely fine.

    Mines the same, Once the CPU reaches 105c it downclocks itself to stay within its limits. Ive noticed the fan doesn't start revving up until the CPU hits 95c on the rMBP and it keeps the fan speeds just fast enough to stay within the 90c range.

    But its normal, don't worry about it.

    You could disable Turbo Boost in bootcamp and use lubbos fan control and you will never again see temperatures above 80c on your rMBP whilst gaming in windows.

    It's quite normal to see temps like these when gaming or other intensive tasks. The Intel processors used in Macs are designed to automatically shut down to prevent damage if they truly overheat. CPU Tjmax = 105C (221F), GPU Tjmax = 100C (212F) on i3, i5, i7 processors. (Source: Intel)

    If you're not already using it, iStat Pro (free) or iStat Menus ($16) will give you accurate readings of your temps and fan speeds, among other things.

    Unless there is a rare defect in a Mac, most temps are well within the normal operating range, considering the workload being put on it. Websites with Flash content, games and other multimedia apps will put higher demand on the CPU/GPU, generating more heat. This is normal. If you're constantly putting high demands on your system, such as gaming or other multimedia tasks, expect temps to rise and fans to spin up accordingly. It's just your Mac doing its job to maintain temps within the normal range.

    It is also quite normal for your Mac to become extremely hot to the touch during intensive operations. The aluminum body transfers heat more effectively than other materials used in computer casings, so you will feel the heat more. This doesn't indicate that it's overheating and will not harm the computer to be hot to the touch.

    Your fans are always on when your Mac is on, spinning at a minimum of 2000 rpm (for MBPs) or 1800 rpm (for MBAs, MBs and minis). iMacs have 3 fans with minimum speeds in the 800-1200 range. They will spin faster as needed to keep temps at a safe level.

    If your fans are spinning up without increased heat, try resetting the SMC.
    (PRAM/NVRAM has nothing to do with these issues, so resetting it will not help.)

    The intake and exhaust vents are in the back of the computer near the hinge on all Mac notebooks (except the new MBP with retina display, which has intake vents along the sides at the bottom). The iMac vent is a slot on the back near the top of the computer. Make sure the vents remain unblocked to allow your computer to perform at its best.
